Common Errors in Fluorescence Spectroscopy
In this post we discuss the phenomena of second order diffraction through a monochromator and the problems it can cause in fluorescence spectroscopy.
Graphene has received tremendous attention within both the scientific community and industry due to its remarkable electrical, thermal and mechanical properties. In this application note, we use the FLS1000 with a Cryosphere accessory to investigate the photoluminescence properties of graphene oxide.
Time-correlated single-photon counting (TCSPC) is a well established and common technique for fluorescence lifetime measurements, it is also becoming increasingly important for photon migration measurements, optical time domain reflectometry measurements and time of flight measurements.
We are lucky to have some holly just outside our factory in Scotland which makes us feel Christmassy all year round. Taking advantage of this we have measured the fluorescence quantum yield of its leaves as a function of temperature, using an FLS1000 with a Cryosphere accessory. The results give information on the photosynthesis process in holly and how it adapts to temp...
Time Correlated Single-Photon Counting (TCSPC) is the method of choice for fluorescence lifetime measurements. In this article, we discuss how the TCSPC technique outperforms all other techniques in sensitivity, dynamic range, data accuracy and precision.
